Real Madrid Castilla have won their promotion playoff against Cadiz.
The Castilla have now returned to the Spanish Segunda Liga after the final triumph.
Young striker Alvaro Morata said: "It's incredible. I've been here many years and I have always dreamt about something like this.
"We are a family and we all deserve it. The last two games showed the attitude the team has. At half-time, the coach said it wasn't done yet. Taking Real Madrid's reserve side back where it belongs is the most beautiful thing there is. I wish to thank our supporters for coming. This is for them."
